Uxcell M4 Serrated Flange Lock Nuts, 304 Stainless Steel, 10-Pack – Rustproof & Vibration-Resistant

About This Product

These little M4 flange nuts are total workhorses.
They come with a built-in wide flange that acts like a washer, so the pressure spreads out evenly over your part.
No more dented surfaces or loosening up over time.
The serrated teeth dig in and lock tight, so even with vibration, they stay put.

Just a heads-up: those serrations mean you can't use them with a separate washer, and they will leave tiny marks on soft surfaces.
But if you need a solid, no-slip hold, these are perfect.

Made from tough 304 stainless steel, they laugh off rust and corrosion, so they're great for indoor or outdoor projects.

Each nut has an M4 thread (0.
7mm pitch), stands 4.
5mm tall, with a 7mm hex width and a 10mm flange diameter.
This 10-piece set gives you plenty for a small job or a few spares for the toolbox.
Whether you're working on machinery, furniture, or automotive fixes, these serrated lock nuts give you that extra grip and peace of mind.
